Abstract

The invention discloses a preparation method of brown yoghourt and the prepared yoghourt. The preparation method comprises the following steps of performing compounding, performing homogenizing, performing sterilization, performing browning treatment, performing inoculation and fermentation, performing centrifugal separation on whey, and performing filling, wherein the centrifugal separation of the whey is performed through performing centrifugal separation treatment on fermented materials so as to obtain the whey and a final milk base material, the centrifugal force adopted by the centrifugalseparation treatment of the whey is 3000-8000 g, and the final milk base material is filled so as to obtain the brown yoghourt. According to the method, any food additives are not used, and through the combination of the browning treatment and the centrifugal separation of the whey, the problems that the brown yoghourt is insufficient in scorch aroma flavor, the technology is time-consuming and energy-consuming, and protein is aggregated in the shelf life are solved.

Description

technical field [0001] The invention relates to the field of food, in particular to a method for preparing brown high-protein yoghurt and the prepared yoghurt. Background technique [0002] In recent years, with the improvement of living standards, people pay more attention to the nutritional components and health functions of food. Yogurt provides rich protein, calcium, vitamins and other nutrients for the human body, improves the balance of gastrointestinal flora, promotes digestion and absorption of the human body, and reduces blood pressure. Cholesterol, enhance the body's immunity, and sweet and sour taste, unique flavor, so popular with people. [0003] With the upgrading of consumption, the team of yogurt family is getting stronger and stronger. In recent years, brown yogurt, as the latest member of the yogurt family, has gradually entered everyone's field of vision. The color change of brown yogurt is actually caused by a chemical change called "Maillard reaction", ...
